1 deck of cards
1. One player goes first by attempting to predict something (value, color, suit) about the card to be turned over. If correct, the player continues, if incorrect - the player drinks, and passes play to the next player.
2. If correct three times in a row, the player can make a rule concerning procedure for the game.
"Can't say red"
"Can't say black"
"Tap head before drinking"
3. If a player is caught "violating" a rule, they drink. But be sure not to break the rules while enforcing them.
